TSK2120A Deep Hole Drilling And Boring Machine

Deep Hole Drilling and Boring Machine

1. Machine Appearance:

 

Machine brief :

2.1 Machine processing capacity :

Drilling diameter range : Φ30~Φ100mm

Boring diameter range: Φ40~Φ200mm

Workpiece OD range : Φ60~Φ400mm

2.2 Machine functions :

Drilling hole : BTA drilling method,remove the cutting chips backward through the drill bar .

Boring hole : Push boring method , remove the cutting chips forward through the basic hole of workpiece.

3. Main parts of machine

Machine bed, headstock, oil pressure head, drill bar support rest , drill box , sliding guide rail , Rack and pinion, coolant system , control system , electric cabinet, workpiece carrier etc. .

3.1 Workpiece clamping

The manual three-jaw chuck on the headstock clamps one end of the workpiece, and the cone disc on oil pressure head automatically tightens the other end of the workpiece. 

3.2 Machine control system

Control system : DELTA PLC

Z axis：The longitudinal feed movement of the drill box, the servo motor drives the rack and pinion mechanism through the reducing mechanism.

X axis: Oil pressure head servo tighten the workpiece , the servo motor drives the rack and pinion mechanism through the reducing mechanism.

3.3 Basic parts

The machine bed , box body, carriage etc. basic parts are precisely cast by super casting iron, processed by twice aging treatment after casting ,to eliminate stress , stable the structure and size , improve the mechanical properties ,etc. .

3.4 Machine bed

The machine bed is made of resin sand and normalised after casting. The bed adopts split structure, assembled with high strength bolts and positioned by cone pin.

Adopt double rectangular sliding guide rail, precision grinding, the guide rail surface is with high quenching hardness.

3.5 Headstock

Used to drive the workpiece to rotate, fixed on the left end of machine bed.

Manual three-gears , speed stepless within gear , the servo spindle motor drives the spindle to rotate through belt and gear box , the manual three-jaw chuck is installed in front of headstock for clamping the workpiece.

3.6 Oil pressure head

Used for guiding the cutting tool, supplying cutting oil and supporting the drill bar .

Servo motor drives its axial movement to adapt the workpiece with different length, and to tighten and loosen the workpiece. The servo motor can work under torque mode or position mode .

The rotary bearings of oil pressure head are installed inside of the oil pressure head box, with good rigidity and high rotation accuracy.

The oil shield is push-pull structure, the oil retention is mounted under the oil shield ,so that the cutting oil can return the oil tank.

3.7 Drill box

Used to drive the cutting tool to rotate, installed on the feeding carriage .

Manual three-gears , speed stepless within gear , the servo spindle motor drives the spindle to rotate through belt,belt pulley and gear box.

3.8 Drill bar support rest

Used to support the drill bar;

Adopt a integrate structure with high rigidity, the support sleeve is mounted on it, which can absorb the impact, vibration, etc. generated during the processing.

Install an automatic hanging mechanism. When returning the tool, the feeding carriage can automatically pull the drill bar support rest back to its initial position.

3.9 Coolant system 

Mainly composed of Cooling pump,chips box,oil tank etc. ,to supply enough cutting oil for deep hole processing.

The pressure, liquid level, oil temperature, and flow rate of cutting oil can be displayed digitally on the control station.

3.10 Feeding carriage

Used for driving the cutting tool to move axially.

3.11 Lubrication system

The sliding guide rail surface of the feeding carriage adopts automatic lubrication station for timed and quantitative lubrication, with a low liquid level alarm function.

3.12 Workpiece carrier

Used for workpiece pre-positioning.

4. Machining accuracy:

4.1 Rough boring and drilling hole :

Hole size accuracy : IT9~IT11

Surface roughness : Ra6.3~ Ra 12.5μm

Hole skewness: 0.5mm/1000mm

4.2 Fine boring hole :

Hole size accuracy: IT8~IT9

Surface roughness: Ra1.6-3.2μm

Straightness of finished hole: less than 0.10/1000mm
